Certificates issued prior to June 1, 2021, are not valid anymore. Please download a new one from the vaccination portal (ocko.uzis.cz). Thanks to the connection to the ISIN, it will appear there automatically as soon as one of the certificates becomes relevant to you.
You can log into the portal
1. by entering the ID card number and birth number. (A text message is sent to you with a code, which you will need to access the portal) and then you can download your certificate. The condition is to state your mobile phone number in the request or just before getting vaccinated. If you do not receive a one-time code or need to change your registered phone number or e-mail, you can contact the toll-free line 1221. This is only a temporary option, available till the end of the year.
2. via an Citizen's Identity solution (in Czech only) (e.g. NIA, MojeID, BankID, a Czech ID card with a chip, etc.), verification via bank identity is possible only for persons who are verified via the population register (ROB),
3. You can apply for a certificate directly at the vaccination point (on request only). This is the best option for children and foreigners not possessing a Czech ID card. Please pay attention when entering your data - it is important to enter the same ones upon each appointment.
